ENVELOPE.-

Applieation filed April '7, 1926. Serial No. 100,330.

It is the present practice for banking institutions to lease What aretermed deposit boxes, to wit, small drawers provided with locks, whichmay be opened by keys furnished tothe lessees. Despite theusnal precautions; itis possible that such boxes may. be fraudulently opened byany employee .of the lessor who has had access to the keys before thedelivery of thesame to the: lessee, and thus had an opportunity ofmaking, or having made, a duplicate or duplicates of the same.

Therefore, the principal'objeet and effect of my invention is to providean envelope with means so constructed and; arranged that it may beutilized to seclude any such original key, from the time ofitsmanufacture until its delivery to the lessee. In the form of myinvention hereinafter described, such an envelope includes a flexiblemember extending within the envelope inclosure, of such character as toengage the key therein, and havingits ends presented exterior to theenvelope Where they may be imbedded ina seal of frangible material; sothat although such key secluding means is in no sense burglar proof, itis of such character as to manifest if any attempt has. been made toopen it, and the fact thatit has not been tampered with, affordsassurance to the lessee that no unauthorized person has had theopportunity of making adu'plicate of the key or keys thus secluded.

My invention includes the various novel features of construction andarrangement hereinafter more definitely specified.

Fig. VI is a longitudinal sectional view of another modified form of myinvention.

Fig. VII is a plan view of theform ofmy invention shown in Fig. VI,showing the disposition of the key holding means with reference tothe'seal. 1

Ineach of said forms of .my invention, the envelope 1 is convenientlyformed of av primarily plain sheet of heavy tough paper having innerflaps 2 and 3 and outer flaps t.

' and 5; said fiapsQ, 3, and i being stuck together with suitableadhesive material and said flap 5, being leftcpen as in Fz'g. I, butprovided with dried adhesive n'iaterial. '7 at the edge. thereofwhichmay be moistened to cause it to adhere to the other .flaps in the closedposition shownin the other figures.

Referring to the form of my invention shown in FigsI to III inclusive;the key holder 8 is conveniently formed of a strip of flexible sheetmet'al,lfor instance, lead or similar dnctile material. Said holder hasits end 9 extending through each of said flaps-'2, 3 and 4 which. haverespective reg-v istered perforations 11 for the same. The. 01 her end12 ofsaid holder 8 prin'iarilv eX- tends 11 arallel with the open flap.5 of the envelope, .butfis adapted to be thrust through theperforation13in said flap 5, sothat the keys 14; and 15 which are connected by thesplit key ring 16 extending through openings 17 therein may be attachedto said holder by slipping said ring over said holder 8, between thelatter and said flaps 2 and 3, as indicated in Fig. III. Thereupon,theend 12 of said holder-'8 may be thrust through said hole 13 in theflap 5; and saidl adhesive Ten. the flap h beingmoistened, said flap maybe folded over and caused to adhere .to the flaps 2,3, and Jr,saidholder 8 being-correspondingly bent in that opera-tion. Thereupon,said end 9 of the holder 8 may be bent over the primarily frceqend ofsaid flapb beneath the end .12 ofsaiitl'holder, and both ends 9 and {12of said holder beuthen imbedded in sealing means, including a body offrangible material 19 such ordinary sealing ax, fused nponthe exteriorof the envelope and. adherent thereto. I

It is, of course, to be understood that the construction and arrangementabove described are such that it is necessaryto break said seal 19 torelease said keys 14 and 15 from the envelope, and that the latter can.-not be ,openedto'aiford access to the keys without disrupting it; sothat any attempt to tamper with the key inclosure described ismanifested by the condition of the same.-

Iieferring to the form of my invention shown in Fig. IV, the key holder21 is conveniently formed ofastrip of flexible sheet till material, forinstance, lead, which has a T- head 22 formed therewith by, flattening abight ofsaid strip. Said holder has lts ends 2%) and 2% extendingthrough the openings tend the end 23 of said strip through anperforation 274m the flap 5. The free end of said flap 5 is thenattached, to the envelope, by its adhesive coating? Said holder is thenbent with its two "ends 23-andf24s parallel with the plane of theenvelope and pressed against the outer'face thereof, and, said ends arethen i'mbedded in sealing means including a body of frangible mate'-rial19 such asjordinary sealing' ivax, fused upontheexterior of tlienvelope and adherent thereto; Ofcourse, such?construction andarrangement render it necessary to break said-seal-19-to'release saidkeys 16L and 15 from the holder 21, and the envelope cannot be? openedtoafford access tosaid-keys with out;disrupting; it;

Referring to the form ofmy invention shown in'Fi'g. V; the keyholderf29- is similar to said key holder'flhbut the T; head 30 thereofextends outside of the envelope 1 and the ends- 31- and 32 of said'holder extend through thefopenings 17 in "the keys 1& and l 5,'witliinsaidenvelope, holding said keys' beneatli the envelope fl'a'p 2-. Saidends extend thence through registered"perfo'ra tions 33in each otsaidflaps 2, 3, l and 5, Said-ends of; the holder '29,'ivhichwere"priniarily straight'and at right angles'to its head-,are thrustthence through the regis tered perforations 33'. in the respectivenvelope flaps fl; 13,4, and 5, and the freepend of thjeflat tei thenattached, to 'tlieenirelope, by its"adhesiveco'atingfii Said eiidsf'ofthe, holder29 are theii ben't parallel with the ou'tcr faceoftheenvelope andIimbedded in sealing means 19, such as above described;Of course, it is necessary to break said sealing meansor disrupt saidenvelope to release the keys frontsaidholder 29f Referring to the formof my invention shown inFigs. VI and VII, the key holder 35 isconveniently formed of a piece of cylindrical wire, primarily shapedlike a hairpin. Sziid holder 3:) is thrust through the openings 17 inthe keys 14 and 15, Said keys are-then'plac'ed Within} the envelopeinclosure and the ends el -saidholde1y35 thrust thence outwardly throughthe registered perforations36in the flaps 2, 3, l, and 5 of saidenvelope.- The tree end ot' said'fiap 5 is then attached to the envelopeby and hesive 7 and the ends-38 and- 39 of said holder 35- are bentparallel with the plane latter, ill such position as to directly en-igage an article w th nthe envelope, hold: the flaps of the envelopetogether and in such pv tioiras to be imbedded in sealingmeansexteriorlo the envelope. Therefore, I 'do not desireto limit myselt' tothd precise deails oi'-constlruction, arrangement, or inethod of-use of;my invention above described, as it is obvious thatvarious modificationsmay be made therein, Without de 'j'arting from the essential featuresotiny invention, asldefined in 'the" appended claims.

I, claim: 1-. The combination with anenvelope formed oi fle xible sheetmaterial, comprising overlapped and adherent flaps and nor; mally open;only at one edge aiidft'here provided-with a closure flap; of; anietallickey holder including a strip of sliee't inet'alfiin cluding abight extending within 'tlieeiivelope inclosure and adapted to 3 thereengage a key, one end of said holdr extendi g out Wardly throiighregistered perforatiens in said overlapped flaps, independently of saidclosure flap, and the other'end of said-holder extending through aperforation in said closure flap ;'sa'idfirst end cream holder beingbent over said closure flap, beneatlr'sai'd other end; and sealing meansincluding a body ot 'frangible material fused-upon the exterior of theenvelope, and adherent;thereto, ai'idinibedding both endsof said holder;whereby it is necesslaify to"break said? a] to release said key't-romsid inclosu're 2. The combination with an envelope formed of;flexiblesheet material; including a normally open closure flap;of akeyholder including aflexible strip forming a tight extending Within theenvelope iiic'losure' and adapted to there hold-a key; one end otsaidholder extending outwardly through a, perforation in said envelope,independentlyof said closure flap, and the other endof said holderextending through a perfoiationin said closure flap;ands'ealingineanslinclud ing a body of -frangible n'iat'er ial fused!upon the exterior of the'envelope', andiadhe fent thereto, and imbeddingboth ends ofsaid holder; wh erel'iy it is necessary to 'hieaksjaid sealto release said-key fromsaidinclosure.
